Courage
I have a correction to your first part of a message<br>
<i>Perl's function bindings are statically scoped, not dynamically scoped, so we can't bind the name to a new entity in a different evaluation context. If we want to play with dynamically scoped entities in Perl, we have to stick to local variables. </i>
<p>Actually you can redefine subroutine by using
<code>eval "sub func {'...'}"</code>
and better yet is just to use anonymous subroutines and use ordinary variables to switch between different ones:
<code>
my $func = sub {
return "value";
};
$func->();
$func = sub {
return "another value";
};
$func->();
</code>
